Application led .Tune 6,

The present invention pertains to a novel stanchion constructed for the purpose of retaining cattle in a given position and preventing their escape therefrom. The principal object of the invention is to provide a device of this character which is readily'adjustable according to the size of the neck of the animal and which cannot be kopened excepty on operation of the device entirely unattainable by the animal.

The invention is fully disclosed by way7 of example in the following description and in the accompanying drawings, in which- Fig. 1 is an elevation of the device;

Fig. 2 is a plan view thereof;

Fig. 3 is a detail end view;

Fig. 4 isa section on the line 4-4 of Figure 1;

Figs. 5 and 6 are perspective views of the locking members; and v l' f Fig. 7 is a detail elevation showing the device of Figure 1in release position.

Reference to these views will now be made by use of like characters which are employed to designate corresponding parts throughout.

In Figure 1 vis illustrated a base member 1 on which are mounted a pair of upright-s 2 and 3. The uprights carry bearings 4 and 5 in which an operating shaft 42 is rotatably supported.

The bearing 5 has an end flange 29, and the adjacent part of the shaft 6 has a head 30 from which extends a neck 31. In the neck is inserted a handle 32 by which the shaft may be turned, and rotation of the shaft is limited by a stop pin 33 fixed to the flange 29. Fur-- ther, the head and fiange have apertures 34 and 35 respectively which are adapted for registration, and a chain 36 fixed to the flange 29 carries a pin 37 adapted to enter the apertures when in alignment.

In Figure 1 there is shown a flexible member 40 wound as at 41 on the operating shaft 42 and lateral chains 43 wound on the shaft as at 44 oppositely to the winding 41. The member 40 and one of the chains 43 support a suspended locking member 45 which is in the form of a double walled member as shown in Figure 6. The inner end of this member is formed atits upper edge with notches 46. A somewhat similar double walled locking member 47 has one end connected to the other chain 43 and its other end formed with a pair of teeth 48 adapted to rest in any pair of opposed notches 46 in the walls of the member 45. Neck bars 49 are passed through the CATTLE s'rnNoHIoN.

members 45 and 47, one of these bars being held' to the member 45by a pivot pin 50 and the other being fixed to the member 47 by a pair of pins 51. A stop pin 52 is carried by one of the bars 49 directly above the pivot 50.

The lower ends of the bars 49 are chained as at g 49a to rods 1LL on the base 1.

To the upper ends of the neck bars are attached double walled and telescopic coupling heads 53 by pivot members 54. The coupling heads are provided with adjustment apertures 55,*and the adjustment is secured by bolts l l56 passed through whichever yapertures are brought into alignment.

The pin 37 vlocks the head 30 to the flange 29' and prevent-s rotation of the shaft, whereby the chains 43 cannot unwind to spread the bars 49. To release the animal, the shaft 42 isturned in the direction to unwind the cable 40 and wind the chains 43. This action tilts the member 45 as shown in Figure 7 and brings it upwardly into engagement with the stop 52 whereby the corresponding neck bar is swung outwardly on its pivot 54. .The lowering of the notched end ofthe member 45 releases .this end from the teeth 48 and frees lthe other bar 49. The winding of the chain 43 connected to the member 47 tends to tilt the member 47 and swing the connected bar 49 outwardly on its pivot 54. The turning of the shaft 42 is continued until the bars 49 have been sufficiently separated to release the animal.

Although a specific embodiment of the 'invention has been illustrated and described, it will be understood that various alterations in the details of construction may be made without departing from the scope of the invention as indicated by the appended claims.

What I claim is:

1. A stanchion comprising a pair of spaced neck bars, coupling heads carried thereby, transverse locking members carried by 'said bars, one of said locking members being pivotally mount-ed and having one end adapted for locking engagement with the other locking member, and a stop member carried by the bar on which the pivoted locking member is mounted, said stop member being engageable by said pivoted locking member, and means for rocking said pivoted locking member.

2. A stanchion comprising a pair of spaced neck bars, coupling heads carried thereby, transverse locking members carried by said bars, one of said locking members being pivotally mounted and having one end adapted for locking engagement With the other looking `member, a stop member carried by the bar on which the pivoted locking member is mounted, said stop member being engageable by said pivoted looking member, a shaft rotatably supported over said bars, ieXible members-connected to the free ends of said pivoted looking member and Wound opposite ly on said shaft.

3. A stanehion comprising pair of s paced neck bars, coupling heads Carried thereby, transverse locking members carried by said bars, one of said locking members being pivot ally mounted and having one end adapted for locking engagement with the other locking member, a stop member carried by the bar on Which the pivoted locking member is mounted, said stop member being` engageableby said pivoted lookingmember, a shaft rotatably supported over said bars, flexible members connected to the free ends of said looking members and Wound in the same direction on said shaft, and

another iieXible element connected to the re engageable by said pivoted locking member,

means for rocking said pivoted locking member, and an adjustable connection between said locking members.

5. A stanchion comprising a pair of spaced neck bars, coupling heads carried thereby, transverse looking members carried by said bars, one of said looking members being pivotally mounted and having one end engaging the other locking member, a stop member earried by the bar on which the pivoted looking member is mounted, said stop member being engageable by said pivoted locking member, a shaft rotatably supported over said bars, fleX- ible members' connected to the free ends of said locking members and Wound in the same direction on said shaft, and another flexible element connected to the remaining end of said pivoted locking member and Wound oppositely on said shaft, and an adjustable Connection between said locking members.

6. A stanehion comprising a pair of spaced neck bars, coupling hea-ds carried thereby, transverse looking members carried b y said bars, one of said looking members beingfpivotally mounted and having one end engaging the other locking member, a stop member Carried by the bar on which the pivotedloeking member is mounted, said stop member being engageable by saidrpivoted looking member, means for rocking said pivoted locking member, and an adjustable connection betvveen'saic heads.

In testimony whereof I affix my signature.
